java.lang.OutOfMemoryError while transforming XmlDocument
------- Additional Comments From [EMAIL PROTECTED] 2001-09-26 07:09 -------
thank you for showing interest in this topic.
question:How do you get Transformers, and do
they get reused endlessly or do you re-get them from prebuilt templates?
Answer: The 'Templates' object is cached in the memory and gets reused for
every transformation. The 'Transformer' is created everytime using the
Templates.newTransformer( ) method. Here is the code snippet which applies the
stylesheet to the XmlDocument object ..
Note: the 'template' object passed on to this method is static and gets
initialized once by the implementing subclasses. The following code snippet is
in the super class [Worker.java] and the method 'applyStyleSheet' is invoked
from the same class by ....
InputSource inSrc = applyStyleSheet( inXml,getRequestTemplate( ) );
where inXml - com.sun.xml.tree.XmlDocument object
and 'getRequestTemplate' is an abstract method implemented by the subclass to
return the static 'Templates' object.
protected InputSource applyStyleSheet( XmlDocument inXmlDoc ,Templates
template) {
Transformer transformer = null;
StreamSource inSource = null;
InputSource outSource = null;
try {
transformer = template.newTransformer( );
inSource = createSource ( inXmlDoc );
outSource = transformSource ( inSource ,
transformer );
} catch (Exception exp ) {
exp.printStackTrace( );
} finally {
transformer = null;
inSource = null;
}
return outSource;
}
